but it doens't. I double-checked everything, rebooted and created the
setup again, notyhing changed it. As soon as I set up the route through
srt0, the outgoing packets for non-local networks seems to fall in a black
hole. I can't see then on any interface.

Anyway with ipf it works, so that's what I'm going to use for now.
